Natsume cant die, if he dies everyones personality will change and not for the better. I can see ruka and many other classmates seeking revenge for his death. and not will only lead them further into a darkness that natsume never wanted for them. and mikan would probably so burdened with guilt she could do nothing to stop them.

Don't bother coming any closer to the darkness that you don't need to see...

if Natsume dies then what is the point of continuing the story of Gakuen Alice when the leading man is dead after making a big promise to the leading lady who is in love with him...... so to summarize it all if Natsume dies it's like saying the manga is dead as well...... right?

NOOOOO !!!

higuchi tachibana will do something about his alice ..
i know he wont die !!
as much as i pity ruka coz he cant have mikan ..
its too much if he dies !! hes for mikan !!

ooh .. and i loove the quote from natsume and mikan ..
soo sweet .. ^-^

i think he won't die cuz either mikan will use her nolification 2 stop him or stealing alice 2 steal it (there might b a problem with stealing it cuz wat if stealing it makes him die sooner?) I DON'T WANT HIM 2 DIE!!!!!!!!!!!
